Perhaps you should try some spelling variations:
"modified network optimisation algorithmssss" » "modified network optimization algorithms", "modified network optimization algorithmsssss", "modified network estimation algorithmssss", "modified network estimation algorithmsssss", "modified network optimization algorithmssss", "certified network optimisation algorithmssss", "defined network optimisation algorithmssss", "modified near optimisation algorithmssss"
"modified objective optimisation algorithm" » "modified objective optimization algorithm", "modified multiobjective optimization algorithm", "modified objective optimization algorithms", "modified objective estimation algorithm", "modified objective estimation algorithms"

Try widening your search to All Fields.

You may be able to get more results by adjusting your search query.

• Performing a fuzzy search may retrieve terms with similar spellings: (("modified network optimisation algorithmssss") or ("modified objective optimisation algorithm"))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: (("modified network optimisation algorithmssss") OR ("modified objective optimisation algorithm")).
• Removing quotes may allow a broader search: (( modified network optimisation algorithmssss ) or ( modified objective optimisation algorithm )).
• Adding a wildcard symbol may retrieve word variants: (("modified network optimisation algorithmssss") or ("modified objective optimisation algorithm"))*.
